Hello KIM people, thank you for checking this site.
Here you can download KIM WKB in zipped OWL format.
It is cleaned against syntax errors, ontology inconsistencies, etc. A great number of warnings, reported by VOwlidator is also fixed. Zip archive with error reports, which I have fixed, you can find here
I have managed to load and edit this owl file into Protege (version 3.2 beta) which can be downloaded here
In order to export this owl file in NT format suitable for KIM, you can use File/Export to format/NTriples
Note: Protege is very consuming application regarding resources. You have to run it on machine with a strong processor and lots of PAMET :)
Change the lax file in Protege Home folder by increasing Heap settings.
Since Protege, cannot load NT files, I had to use Jena 2.2 for that purpose. The good thing is that protege uses Jena, so the export process is fully compatible.
You can download Jena here
I made small java application, which performs Nt2OWL conversion.
You can downloaded zip archive with class and bat file here
At the end, I hope you will find this useful.
